Paper Abstract

The spectra of Nd3+ and Pr3+ doped fiber lasers utilizing two intracore Bragg grating reflectors written at 1084 nm Bragg wavelength have been investigated under 30 MHz resolution. A spectral vernier effect was induced by the subcavities created by reflections from the fiber end faces and from Bragg gratings. We made use of this effect to enhance the sensitivity of the measurement of the fiber temperature rise which arises from absorption of the pump power. Fresnel reflection was also used to reduce the linewidth of the laser emission.
